NE567 Datasheet Tone decoder_phase-locked loop and example circuits

Imagine we want to detect the frequency. But we will use what methods or equipment is appropriate. Choose NE567 is Better. Why? The NE/SE567 tone and frequency decoder is a highly stablephase-locked loop with synchronous AM lock detection and poweroutput circuit. NE567 is good at driving a load whenever the input frequency within its detection … Read more

Transistor equalizer circuit diagram

Here is the transistor graphic equalizer circuit. Why should make this circuit? We use it for controlling the audio frequency in some kinds of audio frequency responses that are not flat. Which we cannot use a normal tone control circuit. Because it has a too wide bandwidth. We need to use a good equalizer circuit … Read more
